Abstract: A pneumatic tire includes an annular tread portion extending in a tire circumferential direction, a pair of sidewall portions disposed on both sides of the tread portion, and a pair of bead portions disposed inward of the sidewall portions in a tire radial direction, and the sidewall portions have an average thickness set to range from 1.0 mm to 3.0 mm at a deflection region of each sidewall portion including a tire maximum width position. The bead portions have a bead base width set to range from 115% to 130% of a tread development width of the tread portion.

Abstract: In a pneumatic tire including a tread portion, a pair of side wall portions, and a pair of bead portions, a carcass layer is mounted between the bead portions, the tread portion has a multilayer structure including a cap tread rubber layer and an undertread rubber layer, and a snow traction index is 180 or more. A tread radius in a meridian cross-section of the tread portion falls within a range of from 80% to 140% of a tire outer diameter, a ground contact width of the tread portion falls within a range of from 66% to 83% of a tire cross-sectional width, and a height of a bead filler is 40% or less of a tire cross-sectional height.
